when authentication is turned on, you will not have access to tools menu, even with admin credentials.
Go to webUI and disable authentication, return to machine, make changes from 'tools menu' then relook after.
hope this helps
I have a 3635MFP here on which -when I log in as admin- there is no tools menu.
Do you know how I can get my tools menu back-as it worked previously-
Regards and thanks
